Blood Letting

You make a melee weapon attack as part of casting this spell. On a hit, the strike deals an additional 2d8 necrotic damage. Additionally, the target begins to bleed profusely. If you choose to maintain concentration, the target takes 1d4 necrotic damage, and their speed is halved for the rest of that turn. This effect ends if you lose concentration, or if the creature is healed in any way. At higher level spell slot usage, this spell's damage increases by 1d8
